Battery Lithium Phaesun Sun Save 12-100 L Underseat

Phaesun Sun Save LiFePO₄ batteries are the ideal solution for anyone who values maximum performance, reliability, and modern comfort in their RV. Specially designed for space-saving installation under the passenger seat, they can be easily used as an upgrade to conventional lead-acid, gel, or AGM batteries.

Thanks to their high energy density, these batteries deliver impressive performance while weighing significantly less. At the same time, you benefit from a particularly high usable capacity ratio, which often means that even a smaller battery is sufficient to ensure the same, or even better, power supply. That means: greater efficiency, less dead weight, and more freedom on the road.

Maximum safety is ensured by the integrated battery management system (BMS), which reliably protects your battery from overloading, deep discharge, and critical temperatures. Bluetooth connectivity also offers real added value: Using the Sun Save app, you can keep track of all important data, such as cell voltages, temperatures and status messages at any time, conveniently and in real time.

Whether you’re traveling, camping off the grid, or using the system in a stationary off-grid setup: with the Sun Save series, you’re choosing a future-proof, high-performance energy solution. The complete package is rounded out by a 5-year manufacturer’s warranty, which offers you additional peace of mind and long-term investment security.

The SunSave 12V series is available in capacities ranging from 100 Ah to 310 Ah.
